Thread Profile Gauge FANAR V0-556000-0000 — 55° and Metric 60° Thread Templates

The FANAR Thread Profile Gauge V0-556000-0000 — 55° and Metric 60° Thread Templates is a handheld reference tool for visual inspection and profile checking of external and internal threads. It provides accurate template profiles for 55° thread forms and metric 60° thread forms, enabling fast comparison of machined threads against standard angles and shapes. The gauge is intended for use in workshops, quality control departments, toolrooms and maintenance operations where quick verification of thread geometry is required.

Advantages

This thread profile gauge offers clear, ready-made templates for two common thread angles, allowing immediate visual assessment without complex equipment. It facilitates detection of profile deviations, incorrect flank angles or worn thread cutting tools by comparing actual threads to the template contours. The portable format makes it convenient for on-site checks and transfer between workstations. The simple design reduces inspection time and supports consistent, repeatable comparisons.

Suitable for

• Visual inspection of external and internal threads
• Quality control checks in production and repair workshops
• Toolroom verification of thread-cutting tools and gauges
• Maintenance and field inspections of threaded components

Key specifications

• Included profiles: 55° thread form and metric 60° thread form
• Format: handheld template for direct profile comparison
• Intended use: external and internal thread profile checking
• Application environments: workshop, quality control, toolroom, maintenance
• Inspection method: visual comparison of thread flanks and angles

How to use

Position the appropriate template contour against the thread to be checked, aligning the template so the flanks follow the profile of the external or internal thread. Observe contact between template and thread along the flanks and crest/root to detect gaps or misalignment that indicate profile deviation, incorrect angle, or wear. For internal threads, insert the template carefully and rotate as needed to inspect the full circumference. Use good lighting and, if required, magnification to improve visibility of small discrepancies.

Usage recommendations

Store the gauge in a dry, clean place to avoid contamination of the template edges. Use the gauge as a quick visual aid alongside dimensional measuring instruments when precise measurements are required. Clean the template before and after use and handle it gently to preserve the profile accuracy.
